I was looking to add a few small outdoor cameras to the perimeter of my house, and this little bullet camera fit the job perfectly. I's less than six inches long, so it has a very small profile, which is good if you don't want the cameras drawing attention.
I installed them on corners, and I get about a 90 degree viewing angle from each. That's more that enough to cover my entire front yard and back yard with just a couple small cameras.
Their 600 TVL resolution delivers a crisp image where I can make out plenty of detail of anyone who comes into my yard, which is the whole reason I wanted cameras in the first place.
I highly recommend these little bullet cameras.
